Residential and commercial fire sprinkler testing and certification services

Our suppression team supports manufacturers, regulatory authorities, building owners and insurance companies with certification and customized testing services for a variety of suppression equipment, including products for residential and commercial sprinkler systems.

Fire sprinkler standards, regulations and requirements

We test and certify sprinklers and nozzles to the requirements in the current editions of the following standards:

  • ANSI/UL 199 Standard for Safety of Automatic Sprinklers for Fire-Protection Service
  • EN 12259-1 Requirements and Test Methods for Sprinklers

Field sprinkler testing

Many communities have adopted NFPA 25 as a referenced standard in their building codes, which are enforced by local inspection authorities. We test sprinklers sampled from field installations as a service to inspection authorities, the sprinkler industry, the insurance industry, and property owners. These test reports aid interested parties in accessing the effectiveness of sprinkler systems, or the need for replacement of sprinklers currently in service.

The Field Sample Sprinkler online portal at Field Sprinkler Program provides a seamless approach for initiating and handling requests. To request this service, use this self-service portal to create an account and to manage testing and reporting on sprinklers from specified locations. Identification tags are also requested through this portal.
